Abstract
Official abstract text for this publication.
Embodiments herein relate to a method for recovering hydrocarbons from a formation including collecting and analyzing a formation sample, drilling operation data, and wellbore pressure measurement, estimating a reservoir and completion quality, and performing an oil field service in a region of the formation comprising the quality. In some embodiments, the formation sample is a solid collected from the drilling operation or includes cuttings or a core sample.
First claim
Opening claim text (preview).
We claim: 1. A method for drilling a subterranean wellbore, the method comprising: (a) drilling the subterranean wellbore; (b) analyzing hydrocarbon gases acquired while drilling in (a) to obtain a log of hydrocarbon gas content and composition; (c) analyzing formation cuttings acquired while drilling in (a) to obtain a chemical composition of the cuttings, the chemical composition including at least one of a mineralogy of the cuttings, a kerogen content, and a kerogen maturit…
